The NSPCC is warning children in West Sussex not to broadcast their location on Snapchat, amid concern it could leave users vulnerable to grooming, stalking and bullying.

Last month the photo-sharing app released its new Snap Maps feature enabling users to share their location with everyone on their Snapchat contacts list to such a precise degree that is possible to tell what part of a building a user is in. The feature also displays if the user is travelling in a car or listening to music.

The NSPCC is urging young people to hide their location using the ‘ghost mode’ setting, and has issued advice to parents. It is also calling on Government to force social networks to offer Safe Accounts to under 18s – with location settings switched off as default.

The charity said Snap Maps could leave users vulnerable to grooming, stalking, bullying, controlling behaviours or feeling excluded. The NSPCC encourages users to think about who is on their Snapchat contact list, and who they are sharing their location with.

Research from NetAware, the NSPCC’s online safety website, found that 36 per cent of young people had added someone online that they don’t know in the last six months.

It comes as police and schools around the country have issued warnings on using Snap Maps.
